For the hoarseness we either gargle with warm salt water or I often use Olive Leaf (Oil) Complex as a gargle and then swallow. I usually take Olive Leaf Capsules along with it and sometimes Oregano Oil to continue to knock out the infections.
I noticed too I can then hit all the high notes again after clearing that crap out of the throat.
We do a lot of ozone here too. We are a combination of different modalities so it's hard to determine exactly what it is that gives it the knock out punch. But it works.
I had a buddy I helped with Hep C (1A genotype) a few years ago and used many of these things including Far Infrared Sauna . I showed my results to two pathologists and they said in 50 years combined research they never saw a drop like that...so either I'm onto something or they really don't care to find an answer. The drop was from 1,067,000 viral count to 2455 in 9 weeks.
Go figure.
Great to type back and forth with you. I certainly hope this helps.
